Allergic reactions are a common discomfort reason any person had to face with at least once. Allergies on the skin can occur both with direct contact with the allergen and as one of the symptoms of an over dosage with drugs.
Allergy on the skin is characterized by an itchy rash of various forms and localization. With contact dermatitis, it is often possible to see the redness of the skin, limited interaction with the allergen. One of the most common elements of an allergic rash is a blister. Contrary to popular belief, it does not have a cavity filled with liquid. The blister is a limited “condensation” of the skin, which is slightly elevated compared to healthy areas. A typical example of a rash consisting of blisters is the consequences of a “burn” with nettle. By the way, that’s one of the most widespread allergic diseases but its symptoms pass by themselves and that’s not dangerous in most cases.
However, skin allergy may also be manifested by a rash of a different nature. For example, a relatively rare disease called “toxicodermia” can be characterized by almost any eruption – from spots to nodules.
Very rarely, allergies to the skin occur in severe form – with the detachment of the epidermis and the formation of blisters. This type of allergic reaction requires hospitalization and intensive inpatient treatment. Skin reactions (redness, the appearance of a rash) are sometimes observed also with anaphylactic shock, as well as with Quincke’s edema.
However, most often, one of the main problems with the appearance of skin allergy is pronounced itch, which sometimes leads to the appearance of scratching, especially in sleep. Of course, when rashes appear on open areas of the body, it also leads to aesthetic discomfort.
When developing allergies, first stop contact with the allergen. Sometimes it is necessary to prescribe medication. Antihistamines are widely used, and preference is given to those of them that are related to the second or third generation and do not cause drowsiness. Among these drugs can be called such as Claritin, Zyrtec. However, these preparations do not lose their relevance: Suprastin, Diazoline (and the latter has almost no sedative effect).
In the possible cases, short-term use of local remedies, such as ointments with glucocorticosteroids – Prednisolone, Hydrocortisone, and others can be the best option. They allow you to reduce the itching and redness of the skin quickly. However, their long-term use can lead to undesirable reactions – skin atrophy, fungal lesions, etc. In rare cases, a systemic administration of glucocorticosteroids is required. An integral part of the allergy treatment regimen is the purification of the digestive tract from allergens and toxins. To do this, enteral detoxication with Enterosgel is used.
To prevent the development of allergic reactions, preparations from the group of stabilizers of membrane mast cells – Ketotifen, Chromogen, and others are prescribed. They do not have a stopping effect, but with prolonged use, reduce the frequency and severity of allergies.
Summarizing, we note that most often, the patient can cope with the allergies to the skin at home. You can enter Tavegil or Diphenhydramine intravenously. If extensive areas of skin are affected, intravenous administration of Prednisone is indicated. If the necessary drugs are not available, you need to rinse the stomach, make a cleansing enema, and give the patient activated charcoal. You also can lubricate the skin with ointment in the area of contact with the allergen containing Hydrocortisone or Prednisone.
However, in most severe cases, hospitalization is required, which is especially true for children.
